COTTON-HARVESTER.

Original application filed March 16, 1900, Serial No. 8,921.

To all whom 'it may concern:

Be it known that I, DON D. Minus, a citizen of the United States,residing at Aurora, in the county of Kane and State of Illinois, haveinvented a certain new and useful Improvement in Cotton-Harvesters, ofwhich the following is a specification.

My invention relates to improvements in cotton harvesters and has forits object to provide a new and improved spiral picking spindle andguide.

My invention is illustrated in the accompanying drawings, w'hereinFigure l is a view of a picking device embodying my invention; Fig. 2 isa longitudinal section of the guide through which the picker passes;Fig. 3 is a section on line s 3, Fig. 2.

Like letters refer to like parts throughout the several figures.

The present application is a divisional ap plication, being part of thesubject matter of a prior application for cotton harvesters made by meMarch 16, 1900, Serial Number other material, but are preferably ofmaterial which will yield, so as to form yielding picking points. Thepicker passes through a spiral guide or wiper device B. This spiralguide may be formed in any desired manner, but is preferably constructedof a tube twisted into a spiral shape. It will be seen that, when thepicker is reciprocated in this tubular spiral wiper or guide, the pickerwill be rotated. In using the device, the guide is preferably held bysome part of the machine and the picker is connected with a moving partof the machine so as to be reciprocated.

In the present case, I have only illustrated the picker and associatedparts and have not Specification of Letters Patent.

Divided and this application filed September 10,

Serial No. 29,552.

shown the machine in connection with which the picker is used, as suchmachine is no part of my present invention and reference is had to myprior application for a description of this machine.

The picker is rotatably connected with some moving part on the machine,as shown at C, so that it is free to rotate when reciprocated. I preferto place the spiral guide B within an inclosing art or tube D, whichholds it in position, said tube being connected with the part E of thecotton harvesting machine in any desired manner. As herein shown, thetube I) is provided with screwthreads and is screwed into an opening inthe part E, the tube being held in place by the lock nut E I haveillustrated a particular construction embodying my invention, but it isof course evident that the parts may be varied and I therefore do notlimit myself to the particular construction illustrated.

The use and operation of my invention are as follows: When the device isbrought in proximity to the cotton, some means is provided forreciprocating the picker in the guide or wiper device B. Thisreciprocation produces a rotation of the picker. The engaging or pickingpoints A then become entangled in the cotton so as to remove it from theplant. hen the picker is withdrawn or retracted into the part B, thecotton is wiped 01f or removed from the picker and may be handled in anydesired manner. It will be seen that the spiral guide B acts as a. meansfor rotating the picking spindle when reciprocated and also acts as awiper device to remove the cotton therefrom.

The outer tube D is provided at each end with end-pieces connectedthereto and provided with slots into which are received the flattenedends of the spiral tube B. The end-pieces act to fasten the spiral tubeB to the outer tube D so as to form a. unitary structure which can behandled as one piece.

I claim:

1. The combination with a spiral picker of a spiral guide through whichthe picker passes, a tube surrounding said spiral guide, and means forfastening the spiral guide to the outer tube so as to form a unitarystructure.

2. The combination with a spiral picker of a guide comprising a tubetwisted into a spiral an outer tube surrounding the spiral tube,end-pieces at each end of the outer tube provided with slots into whichthe ends of the spiral tube are received.

3. A guide for spiral cotton pickers comprising an outer tube, anend-piece at each end of said tube, said end-pieces provided with slots,a spiral tube Within the outer tube having its ends contained Within thesaid slots, so that the spiral tube is supported by the end-pieces.

4. A guide for spiral cotton pickers comprising an outer tube, anend-piece at each end of said tube, said end-pieces provided with slots,a spiral tube within the outer tube having its ends contained within thesaid slots, so that the spiral tube is supported by the .end-pieces, asupport having a screw threaded opening, the end of the outer tube beingscrew threaded and fitting in said opening.

5. A guide for cotton pickers comprising a spiral tube through which thepicker passes, an outer tube surrounding said spiral tube, the two tubesconnected together, a

support to which one end of said outer tube is connected, the other endbeing free.

6. A guide for spiral cotton pickers comdicular to said support.
